Tcp Performance Evaluation over a Dvb-rcs Satellite-haps Integrated System
نویسندگان
چکیده
An integrated satellite-HAPS system is particularly suitable for supporting emergency communications. A key element for the efficient adoption of such systems is the enhancement of transport layer capability to support TCP-based applications. This paper proposes a detailed analysis of TCP performance over the target scenario, involving a DVB-RCS protocol stack for satellite air interface. I-PEPs play a fundamental role in improving transport layer performance thanks to advantages coming from both TCP splitting adoption and the use of an optimized transport protocol over the satellite link. Ns-2 simulations have supported the overall analysis.

TCP and Link Layer Enhancements in DVB-S/DVB-RCS satellite systems
[email protected] ABSTRACT The Transmission Control Protocol (TCP) is efficient on wired networks, but provides poor performance on satellite networks due to the specific characteristics of satellite links. In this paper, we present the experiments results for a combined approach of a selected set of state-of-art TCP enhancements in conjunction with link layer enhancements. Link laye...
متن کاملAnalytical Approximations of the TCP Round Trip Time over DVB-RCS Architectures
This paper evaluates the effects of bandwidth asymmetry introduced in a geostationary DVB-RCS satellite architecture on the Round Trip Time of the Transmission Control Protocol (TCP). In particular, it shows the analytical analysis of the round trip time (RTT) of a TCP connection and defines a bandwidth asymmetry index, which is the key point of the work. The final goal is the provision of anal...
متن کاملTCP behavior in a DVB-RCS environment
In 2000, ETSI has approved and published a standard for interactive broadband satellite services (DVB-RCS) . One of the most important features of this standard is the implementation of DAMA strategies aiming at a fair and efficient use of the shared resources in the satellite return channel. A DAMA scheme introduces a new control loop, based on a signaling exchange between STs and the NCC, ins...
متن کاملPerformance Assessment Using Acm in Dvb-s2/advanced Dvb-rcs Satellite Systems
This paper presents the benefits of using adaptive coding and modulation in DVB-S2/advanced DVB-RCS satellite systems. The results are based on a satellite system simulator which was developed during an ESA study. Such a simulator aims at making performance assessments before implementing a system, at developing and evaluating new algorithms like schedulers, encapsulators or resource managers. ...
متن کاملAir-born Satellite Emergent Transmission System based on Civil DVB-RCS Technical Scheme
The return link performance of conventional civil DVB-RCS transmission technology limits its direct application to air-borne satellite video transmission system. This paper studies the novel emergent DVB-RCS return link technique based on introducing adaptive parallel processing to the conventional civil DVB-RCS return link. Simulation results demonstrate that the proposed return link transmiss...
